## Abstract

An automatic pool cleaner including a body, an elongated member connected to the body, the elongated member having two fluid flow paths, a valve mounted for alternately directing the flow of fluid between the fluid flow paths, the upper ends of the two fluid flow paths being connected together by an arcuate passage in a first plane substantially co-planar with the elongated member, and the arcuate passage connected to at least one arcuate outlet passage in a second plane at an angle to the first plane.

## Claims

### Claim 1

An automatic pool cleaner comprising:
a body;
an elongated member having an axis, said elongated member being connected to said body, and having two fluid flow paths therein;
a valve mounted relative to said elongated member for alternately directing the flow of fluid between the two fluid flow paths;
an arcuate passage;
the upper ends of the two fluid flow paths being connected together by said arcuate passage in a first plane substantially co-planar with the axis of the elongated member; and
said arcuate passage connected to at least one arcuate outlet passage in a second plane at an angle to the first plane.

### Claim 2 (depends on 1)

An automatic pool cleaner as claimed in claim 1 wherein the at least one arcuate outlet passage is located in a plane substantially at a right angle to the plane in which the flow paths of the elongated member are located.

### Claim 3 (depends on 1)

An automatic pool cleaner as claimed in claim 1, wherein two arcuate outlet passages are provided, oppositely disposed on opposite sides of the arcuate passage.

### Claim 4 (depends on 2)

An automatic pool cleaner as claimed in claim 2, wherein two arcuate outlet passages are provided, oppositely disposed on opposite sides of the arcuate passage.

### Claim 5 (depends on 1)

An automatic pool cleaner as claimed in claim 1, wherein the two fluid flow paths are passages in said elongated member.

### Claim 6 (depends on 1)

An automatic pool cleaner as claimed in claim 1, wherein the two fluid flow paths are tubes in said elongated member.
